SL55 ECM

I had a fan run on high issue and coolant light on.
i followed all the advise here step by step.
I swapped a ECU from my 2003 into my 2006 as was suggusted. The fan operated fine. I sent my ECU to Pressortech to be tested and if possible repaired. I changed the coolant temp sensor, A/C pressure sensor, and other relays before sending it out. I will post the results thanks for the help.
P.S I cannot drive my 2006 Sl55 because it got keyed and the hood is at the shop. The Sl500 is awaiting a new fuel disturber. Now I have to drive around in my truck in this nice Florida weather.

You are going to love the Pressertech ECU Flash. While I did the Phase 1, I can only imagine that the Phase 2 must be a blast! I'm sure your issues will be gone after Todd is finished. Enjoy your car

I have heard only good things about them. He is very easy to talk to and is in no rush to get you off the phone. They are going to see if it's repairable if not he will clone one for me. The price will be much cheaper the MB

I sent mine in for repair. I talked with the tech and enquired about the stage 2. I have looked around on this site and found that most folks see massive performance gains and are very pleased they had it done. The cost is I believe is around $1000 but I could not here him because the noise level at my location. I am going to get it done on the 03 SL55 once I finish the 06 and sell it. Also on the 03 I am installing the VVK strut and sway bar conversion.
